| Abstract | In this study, an improved cuckoo search (ICS) algorithm is presented to solve the parameter estimation problem of soil structure. For 1D soil parameters estimation, the objective function is constructed based on the relative root-mean-square error between measured and calculated soil apparent resistivity curves. The ICS algorithm extends the search range of soil model parameters through variable control parameters. Optimal resistivity and thickness of each layer are obtained by several different algorithms under the same test conditions based on two known four-layer soil models without noise. The results show that the ICS algorithm performs better in minimising error. This study also tests the optimisation performance of the ICS algorithm in two actual high-quality data cases, comparative results of the ICS algorithm and existing literature validate the effectiveness and accuracy of ICS. Moreover, in order to make soil estimation results more visible in a specific area, the combination of the proposed estimated algorithm and a new arrangement way of measurement lines is proposed to estimate 3D soil electric parameter structure in Chengdu, China. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
